Figure' 3 is `an enlarged elevation of thel planter unit; and, l v i ,YFigure 4 shows an adjusted position of the seed mechanism supportingframe. j 'The tractor illustrated is of a conventional constructionhaving side frames 10,v

rear driving wheels 11, andforward steerable Y wheels l2; The wheels 12are mounted on a steering. column 13. A cross frame member 14 ispositioned at the vfront of the frame .10.

A shaft l-is-.seoured by brackets tothe cross member 14; The member 15is adapted to` extend across the front of the tractor in order toprovide for attaching units at .each side of thetractor. As each `unitis exactly similar, only one sideis shown in the illustration. Adownwardly, rearwardly extending beam 16 is pivotally attached on atransverseaxis by a connecting member ,17 lto the shaft `15. The beam?16 has'a substantially horizontalexten-sion 18 to whichthe planter unitis attached. A bracket `19 is rigidly atportion 18. Bars 20 arepivotally attached-.to opposite sides .of thel bracket 19 and extenddownwardly and yrearwardly therefrom. The bars 20 are attached to andhold inoperative position a furrow opening and seed depositing member21. :A pair of upwardly extending plate members 22 provided with a`series of aligned openings 23 provide means for supporting the Vbase24`of the `seed dispensing mechanism. The base24 is, pivoted on atransverse axis to the plates 22. The open'- ings 23 are spaced,lthereby providing` means 'for adj ustingthe forward endof thesupporting base vertically.` A `bracket ..25 mounted at the rear end`ofthe `horizontal portion 18 of the beam 16` is provided with alaterally extending, `aperturedy ear 26.

Arod 27 having a flattened head 28, which is pivotally attachedatvthe-side'iof. one of the vplatemembers 22 on a horizontaly axis,^ex

tendsthroughthe aperturedear 2b.` .Arkey collar 29, is fitted on theendof the rod 27 above the ear- 26. A collar '130 positioned on therod28 forms a stop' against which one end of a compression springl abutsrThe other end `of the compression spring abuts againstthe lower surfaceof theear 26.` `,It

will be 4understood that by Vthis construction the bars 22'mfayzmovetoward the beamv 16 against the compressionofthespring 31, the

spring normally holding said lmembers apart p the angular distancedetermined l.by the length of the rod 27. 'y j. i j

A link 32 is" `pivotally attached vto the bracket 25 and to ajbracket 33mounted on a bar 34 extending horizontally from theffror'it of thetractor to aposition at therear thereof. yThe frontof the,bar` 84 ispivotally mounted on .a link 35,`which may be oscillated about the shaft15.. kThe rearjend of the` bar 34 is mounted ,for reciprocation inany1well known manner for lifting and Iloweringthe beam-'16, whichcarriestheplanter mechanism.v w 'j y A shovel'SG carried on a shank 37is rig-idf'- ly attached vby a bracket 38 to therearw'ard extensionofthe beam 16. ,This shovelfmay be of any desired constructionforagitating` the soil in` front o f :the furrow opening means. A member39, which is constructed as a casting, is pivotally secured on atransverse aXis at the rear of-the bars 20. Upwardly and rearwardly fromsaid pivot axis,

the member 39 is also pivotally connected by a member to the rear of thebase 24, whichV supports the seeding mechanism. The

member 40 has an integral extensionV 41,A

Y ywhich is provided Ywith a clamping'. means 43 @of .the member 39.

for adjustably engaging an arcuate sector 44 formed on the member 39.This adjustment forms means for raising and lowering` the position ofthe furrow opener 21.with respect to the surface ofthe soil. l j

' A rolling support is provided at the rearV Said support'consists of'apair ofwheels 45, rwhich are ymounted face'is provided adjacent the slot48-against Y on= the downwardly bentv ends ofan axle 46,

` so Ythat the wheels are positioned at an angle` with respect to eachether. The wheels 45 haverrims, which are tapered inwardly to Vprovide'meansfor covering the furrow and packing the soil firmly in position.`A shaft 47 is secured to 'jthe axle 46'ande1tends radially therefromthrough a Aslot 48 in the ortion of the member 39 which forms theearing-forthe axle 46 A roughened sur- V`whichamember 49 mounted on theshaft 47 may bfetightly pressed by a shoulder 47LL on the shaft 47, tohold the axle-'46 against rotation with respectto4 its bearing support.yIt

will thus be seen 'that means v'is thereby ypro-` vided for adjustingthe aXl'e 46 with respect to the member 39,' whereby the bent endsvonwhich the wheels 45 are mounted are given va different-V angularposition. In-this manner, the portions of the wheels on the ground arevaried, so that the wheels are' narrowery or wider apart. This isdesirable for different conditions of planting.

The base'24 carries a small seed hopper 50 and seeddispensing.mechanismof a conventional nature, not shown, as it is not apart of this invention. `A shaft 51' mounted below the base 24is-adapted to operate .the seed` dispensing mechanism. VA toothed wheel52` Y is mounted onthe shaft 21 'andv is adapted to engage the soilwhereby the shaft 51'is rotated during movementY of the-tractor. AV

-se'e'd spout 53 is pivotally mounted beneath theb'ase'24 and Vextendsinto the top of the seed depositing member 21. An extension 54 below thebase 24 provides means for deliver'- ing the seed from thedispensingmechanism into the spout 53. The seed hopper k is mounted on a base 55,which is hingedy at one sideto the base 24. VAtrvthe otherv side, aclamp 56 is provided for holding the hopper securely in position. Aflexible seed tube 57 nis/secured' to the top of the .seedhopper 5() andto the bottoml of Va relatively large seed supply hopper or tank 58,secured by a bracket-59 tothe tractor frame f In Operation" of thisdevice, the planterfv unit is lowered into position by the operation ofthe bar 34 to lower the link 32. Y

Vheels 45 engage the ground and the shovel 36 operates at a level gaugedby the wheels 45. Y The furrow opening and seed depositing member 21also operates at a depthl -gauged by the wheels 45. When it is found`desirable Yto change the depth of planting,

the clamp 43 is'loosene'd and the extension 42 is mounted about' thesector 44.`

The toothed wheel 52 engages the ground and operates the seeddispensingmechanism.V

Seed delivered at uniform intervals drops down through the seed spout 53into the'fur- Y row opening and seed depositing member 21. The plates22, which form the front 'support for the seed dispensinglmechanism, byreason of thek spaced openingsl23, provide means f y for verticallyladjusting the frontend of the base 24. By this adjustment, thefdepth atwhich the toothed wheel 52 lengages the ground may be varied. Itisdesirable to have said wheel engaging the ground 'sufficiently to obtaina positive uniform operation of the seed mechanism; however, the 'wheelshould not engage the ground suiiiciently to havevthe tendency to raisethe planter mechanism up?` d wardly.

The spring 31 provides means for resiliently pressing the planter unitdownwardly into engaging position'. At the vsame time, the

said spring, togetherwith the rod v27,-proi* lvide means for permittingthe planter unit l to raise vertically whenl an obstruction'is en'-,A1160 It will he understood that applic-ants have. j
